Description

If an application does not properly restrict data writes to allocated memory locations, a threat actor could send an input or message that writes data outside of intended or allowed memory locations. By overwriting memory locations, an attacker can possibly hijack the control-flow of the program to remotely execute their own code or cause a DoS on the device.
